MP 1,1-5,1 Sequoia on a 3,1. What We Know.

On both installs, Safari 18.4 is not working. When I try to go anywhere on the Web, I get an error saying "A problem repeatedly occured with ....(URL)"

Firefox (latest download) is working fine.

Is that a known issue with a 3,1?

Also with any other Mac that does not have AVX/AVX2 support - Safari JIT now requires AVX support, did you try disabling it?

P.S.:

Disabling is setting it to false.

I did new "clean" installs on my 3,1 today. Have Sonoma running on one SSD and Sequoia running on another one.

no, I think latest Safari uses AVX2 or some instructions the macPROs don't have. Same with 5,1, supposedly. I am on 15.3.1, which has Safari 18.3 and it works fine. I believe you can dl it from Apple somewhere and downgrade.

I can run Safari 18.4 with no problem on my 4,1/5,1, using OCLP and Sequoia.

On my 3,1,running either Sonoma or Sequioa, 18.4 as configured out of the box, it fails. So I stick with Firefox.

It’s one of the few fails that I’ve found on my 3,1 while running Sequoia.

i meant what does the icon do when you double click it?

Well, seems of all the things I've tried to consistently get Sequoia to boot with both cpus, booting windows 10 (legacy) first, then rebooting to sequoia seems to be the most foolproof! LoL! Not sure what win 10 legacy is doing to nvram, smh or other but it has been the most foolproof method as of yet. Crazy machines these 3,1s! 🤣
